AXN320038S Equivalent & Substitute Parts

Part Overview

The AXN320038S is a 20-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with center strip contacts and gold plating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The connector features a 0.031" (0.80mm) pitch configuration with dual-row arrangement and board guide features, operating at mated stacking heights of 3mm, 4mm, and 5mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXN320038S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Socket, center strip contacts
• Number of positions: 20
• Number of rows: 2
• Mounting type: Surface mount
• Contact finish: Gold
• Features: Board guide
• Moisture sensitivity level: 1 (Unlimited)

Secondary Consideration:

• Pitch tolerance: Substitute parts must maintain mechanical and electrical compatibility with mating connectors designed for the original pitch specification

The AXK5S20037YG qualifies as a substitute based on matching all primary compatibility criteria. However, the pitch specification differs (0.020" versus 0.031"), which represents a distinct mechanical characteristic that must be evaluated within the context of the specific application and mating connector requirements.

Parameter Comparison

Engineering Selection Recommendations

The AXK5S20037YG is listed as an active product with RoHS compliance status, providing regulatory advantage over the obsolete AXN320038S. Both components share identical connector type, position count, row configuration, mounting method, contact finish, and board guide features.

The pitch differential (0.031" versus 0.020") and height variance (0.087" versus 0.120" above board) represent measurable design changes that require verification against the specific application's mechanical and electrical requirements. The substitute part operates within mated stacking heights of 4mm, 5mm, and 6mm, compared to the original part's 3mm, 4mm, and 5mm range.

Selection of the AXK5S20037YG should be based on compatibility with the mating connector pitch specification and available board space for the increased height above board dimension.

Frequently Asked Questions (FAQ)

Q: Can the AXK5S20037YG directly replace the AXN320038S in existing designs?

A: Direct replacement requires verification that the mating connector is designed for 0.020" (0.50mm) pitch and that the increased height above board (0.120" versus 0.087") does not create mechanical interference within the assembly.

Q: What is the significance of the pitch difference between these parts?

A: Pitch defines the center-to-center spacing between contact positions. The AXN320038S uses 0.031" pitch while the AXK5S20037YG uses 0.020" pitch. These are incompatible with each other's mating connectors and cannot be interchanged without corresponding changes to the mating connector.

Q: Why is the AXN320038S listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AXK5S20037YG represents an active alternative from the same manufacturer within the rectangular connector socket category.

Q: Are there packaging differences between these parts?

A: The AXN320038S packaging is not specified in the available data. The AXK5S20037YG is supplied in Tape & Reel (TR) format.

Q: Do both parts meet the same moisture sensitivity requirements?

A: Both components are rated at Moisture Sensitivity Level 1 (Unlimited), indicating equivalent moisture handling specifications.

Q: What compliance certifications apply to the substitute part?

A: The AXK5S20037YG is RoHS Compliant and REACH Unaffected. The AXN320038S compliance status for these certifications is not specified in the available data.
